Here are the features of a 100ml Stopper Cylinder (volumetric flask) with descriptions:
1. Capacity: 50ml - The volume of liquid that the flask can hold.
2. Material: Borosilicate glass - A type of glass that is resistant to thermal shock and chemical corrosion.
3. Shape: Cylindrical - The flask has a cylindrical shape with a flat bottom and a narrow neck.
4. Stopper: Ground glass stopper - A stopper made of glass that is ground to fit precisely into the neck of the flask, creating a secure seal.
5. Graduations: Precise markings - The flask has precise markings to indicate different volumes, allowing for accurate measurements.
6. Accuracy: Class A or Class B accuracy - The flask meets the highest standards of accuracy for volumetric measurements.
7. Chemical resistance: Resistant to corrosion from most chemicals - The flask can withstand exposure to a wide range of chemicals without being damaged.
8. Thermal shock resistance: Withstands extreme temperature changes - The flask can be used at a wide range of temperatures without breaking or shattering.
9. Autoclavable: Can be sterilized in an autoclave - The flask can be sterilized using high-pressure steam.
10. Durable: Long-lasting and resistant to wear and tear - The flask is designed to withstand regular use and cleaning.
